LETTER OR BILL FILE.

SPECIFICATION formingpart of Letters Patent No. 602,838, dated April 26, 1898.

Application filed March 1, 1895. Serial No 540,251. [No model.)

To all whom it may concern.-

Be it known that I, SEIGLE DRUMMOND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Letteror Bill Files, of which the following is a full, clear, and exact specification.

My invention relates to that class of files which have rotatable guard-wires for preventing the accidental withdrawal of the papers from the impaling-pins.

The object of my invention is to greatly simplify and improve the construction, operation, and arrangement of the mechanism for holding the guardwires in their proper positions.

With these ends in view my invention consists in certain features of novelty described and claimed herein and shown in the accompanying drawings.

In the said drawings, Figure l is a plan view of my improved file, the guard-wires being shown in their outward position in dotted lines. Fig. 2 is a vertical longitudinal section taken on the line 2 2, Fig. 1; and Fig. 3 is a bottom plan with the board removed.

Like signs of reference indicate like parts throughout the several views.

1 represents the base-board, upon one end or" which is secured a casting 2, which may be provided with the usual eyelet 3, by means of which the file maybe hung up. The casting 2 is preferably a box-like structure, hav-' ing formed on its inner side two bosses 4, which project inwardly within a short distance of the bottom plate 5, the latter being secured to the under side of the casting in any suitable way. The bosses 4 are each provided with a central bore, through-which passes the usual guard-wire 6, whose inner end protrudes slightly beyond the lower end of the boss and has swaged or otherwise secured against rotation thereon a crank-arm '7.

when the guard-wires 6 are resting against the impaling-pins in their normal position, as shown in Figs. 1 and 2, the crank-arms 7 are supposed to be turned backward a little beyond a straight line drawn through the centers of the bosses 4, and when the guardwires are in their thrown-off position, as

shown in dotted lines in Fig. 1, such crankarms are supposed to be deflected to the 0pposite side of such line, as shown in dotted lines in Fig. 3. In order that the crank-arms may be held in either of these positions, as desired, and the guard-wires 6 held in or out of their normal positions, I crowd between these crank-arms, so as to form a bearing against both, some suitable form of cushion, which as soon as the ends of the arms pass the center on one side will throw them to the extreme of their movement on that side. As a simple and efiective means of accomplishing this I employ a coil-spring 10, whose ends are inserted over the stems 8, respectively, the spring being slightly compressed while in either of the positions shown in Fig. 3, so as to exert a normal tendency to deflect the arms in the direction in which they are turned, thus holding the spring in place and prevent ing the guard-wires from returning to their normal position without the application of pressure from the hand of the operator. The spring 10 is sufficiently less in diameter than the space between the top of the casting 2 and the plate 5 to permit it to oscillate therein without striking either of such parts.

11 represents in dotted lines the bills or papers on the file.

12 represents a binding wire passing through opposed slots in theinner sides of the hollow impaling-pins 9 and having their ends coiled in said pins, as fully shown and described in United States Letters Patent No.

586,134, issued to William Lumley July 13, 1897, to which reference may be had for an understanding of this feature, which constitutes no part of my present invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the impalin wires, and the verticallypivoted transfer- Wires, of a bodily-movable normally-bowed combined spring and motion-transmitter connected at its ends to the pivoted portions of said transfer-Wires, substantially as set forth.

2. The combination with the impalingwires, and the vertically -pivoted transferwires, of separated arms or members projecting inwardly from the pivotal portions of said transfer-Wires, and an intermediate bodilymovable spring connected at its ends to said arms or members and serving to transmit the motion from one transfer-Wire to the other, substantially as set forth.

3. The combination with the impaling-pins and rotatable guard-wires, of crank-arms on said guard-Wires projecting toward each other, and a coil-spring having its ends inserted over and crowded between the ends of and being held in place by said crank-arms, substantially as set forth.

4. The combination with impaling-pins and rotatable guard-wires, of crank-arms on said guard-wires turned toward each other, and having stems on their inner ends, and a coiled spring having its ends inserted over said stems, and tending to force said crank-arms apart, substantially as set forth.

5; The combination with impaling-pins and rotatable guard-wires, of acasting having the bosses 4, in which said wires are journaled, crank-arms on said wires having their free ends bent upward, and a spring crowded between and coiled up over said ends, substantially as set forth.

SEIGLE DRUMMOND.
